François Cyrille Grand'Eury

François Cyrille Grand'Eury (9 March 1839, Houdreville – 22 July 1917, Malzéville) was a French geologist, paleontologist and mathematics teacher.

He studied at the École Loritz in Nancy and at the École des mines in Saint-Étienne, and later worked as a mining engineer in Roche-la-Molière.[1] From 1863 to 1899 he taught classes in mathematics at the École des mines in Saint-Étienne, where in 1883 he received the title of professor.[2]

From 1877 he was a member of the Société géologique de France and in 1885 was elected a correspondent member of the Académie des Sciences.[2]

He is remembered for his stratigraphic research of coal fields and for his investigations involving the formation of coal. He is credited with establishing the chronological succession of floras associated with the coal seams of the Stephanian stage (named after the development of this stage at Saint-Étienne). He conducted exhaustive studies of coal flora (Cordaites, Calamites, et al),[3] and in 1877 described the genus Tubiculites.[4]
